I just got my electric EZGO golf cart up and running this morning. I test ran the cart on and off jack stands. Everything ran great. I pulled it into my garage went to take the spouse for a ride and nothing but the solenoid click. I put in new batteries, new controller, basically everything new except the 0-5k throttle. Yes I did go with the Curtis knock off, If I can get 6mos to a year out it then great. Battery pack read 50v. Is it possible that the battery pack voltage is too low? I didn't charge them at all yet, charger is being delivered tomorrow. It ran about 16mph on the stock motor, still have to see how it is on the hills.
